Product Details

The Brembo GT-S Big Brake Kit with slotted rotors is a disc brake upgrade kit for drivers who want stronger, more consistent stopping power for spirited street driving and occasional track days. Built around Brembo's fixed-caliper design, this big brake kit replaces the factory calipers and rotors with higher-capacity components.

Key Features:

  • Fixed monobloc-style aluminum calipers provide a stiff, rigid clamping platform for a firm pedal feel and consistent pad pressure.
  • Slotted rotors help clear gas, dust, and water from the pad surface for dependable bite and better wet-weather response.
  • Larger-diameter rotors add swept area and thermal capacity to help resist brake fade during repeated hard stops.
  • Multi-piston caliper design spreads clamping force evenly across the brake pad for more controlled braking and even pad wear.
  • Brembo engineering draws on the company's motorsport experience and OEM supplier background.

Designed as a bolt-on upgrade, the GT-S series balances performance, appearance, and everyday drivability. The kit gives a clear improvement in pedal feel, stopping performance, and heat management over stock brakes. Component specifications and contents vary by application, so refer to the individual item listing for details.
